Matrix Switch

摘要

Four SP4T switches ( 3 ₁- 3 ₄) are grouped in twos to form two switch pairs. First conductive lines ( 4 ₁₁- 4 ₁₄ , 4 ₂₁- 4 ₂₄) are arranged in fours between the SP4T switches ( 3 ₁ , 3 ₄ ; 3 ₂ , 3 ₃) constituting the switch pairs. Each of four second conductive lines ( 5 ₁- 5 ₄) connects to a corresponding one of different conductive lines of the first conductive lines which connect to the respective switch pairs. The first and second conductive lines are arranged on a dielectric layer having a lower surface on which a ground conductor ( 6 ) is formed. The dielectric, layer has a two-layer structure. The first conductive lines are arranged on the first dielectric layer as a lower layer. The second conductive lines are arranged on the second dielectric layer as an upper layer. This arrangement makes it possible to attain a reduction in the size of a matrix switch and a reduction in loss and allow broadband operation.
